This invention relates to a metal corner bead for use in buildings, andhas for its object to provide a superior corner bead at a minimumexpense. To this end, the corner head is provided with a substantiallyflat body portion from which extend arms or legs, which normally lie inthe plane of said body portion and which are spaced apart a distancesubstantially equal to the width of one 'of said arms, and the latterare then cut to form tongues or fingers, which are bent or foldedsubstantially parallel with the arms to form extensions of the latter,and thus provide the corner bead with-arms which are of the desired orstandard length and composed of members or sections of different widths.The arms thus formed are bent at an angle to the plane of the bodyportion with alternate arms on opposite sides of said plane. The bodyportion is preferably provided with a longitudinally extended fold orbead, which projects on opposite sides of the plane of the body portionso as to provide a substantially T-shaped body portion of maximumstrength. The tongues or fingers being formed from the arms or legs,leave a space or opening in the arms for the entrance of plaster, andthe corner bead is thereby provided with bonding apertures between thearms or legs and additional bonding apertures in the arms themselves,whereby a superior bonding or adhesion of the plaster to the corner beadis obtained.

The particular features of this invention will be pointed out in theclaims at the end of this specification.

Figs. 1. 2 ands, (0 represents the substantially flat body portion,which is of substantial width and is for the best results pro vided atone edge with a longitudinally extended fold b forming a hollow bead,and said body portion has extended from'its other edge a plurality ofarms'or legs 0, which are spaced apart and separated by spaces (Z of awidth substantially equal to the width of one of ti e arms or legs 0 Thecondition of the corner bead as thus far described isillustrated by Fig.3. The arms or legs 0 are then cut in a manner well understood, to formtongues or fingers 10,

which are of sufficient length to enable them to be bent and foldedsubstantially parallel with the arms cand to project beyond the loweredges of the latter, as represented in Fig. 5. The arms 0 and theirprojecting fingers 10 are then bent at an angle to the body portion a,and preferably alternate arms and fingers are bent in oppositedirections, so that they extend on'opposite sides of the plane of thebodv portion a, as repre-v sented in Figs. 1, 2 and 6, in which condition, the corner bead is ready for applica tlon to the corner of thebuilding 12, to

which it is secured by nails or like fastening devices driven throughholes 13 in the fingers 10. V

By forming the fingers 10 from the arms or legs 0, and folding thefingers so as to width of the arm 0 multiplied by the dis-' tance thefinger overhangs the lower edge of the arm or leg 0. r V p It will alsobe noticed that when the fingers 10 are formed, there is left in thearms 0 openings 14 into which the plaster r can enter, and theseopenings together with the spaces (Z provide the corner bead withbonding apertures, by means of which a superior bonding of the plasterto the corner bead is obtained. It will be observed also that the arm ais materially shorter than the length of the arm plus that of thefinger, and said arms are separated by spaces of a width substantiallyequal to that of one of the arms, and, as a result, two corner beadshaving arms or legs of standard length can be made from a sheet metalblank of minimum width without waste and at a material saving in cost,which is highly important from a commercial view point. The corner beadmay be made in sections of any desired length within limits.

Claims:

1. A metal corner bead section provided with a substantially flat bodymember folded at one edge to form a longitudinally extended bead andhaving arms extended from its other edge at an angle to said bodyportion and normally lying in the plane of said body portion withadjacent arms spaced apart by a distance substantially equal to thewidth of one of said arms, and which forms a bonding opening for plasterbetween the arms, fingers integral with said arms and struck therefromand normally lying in the plane thereof, said fingers being foldedsubstantially parallel with said arms and projected beyond the loweredge thereof to form therewith arms of a predetermined length but ofdifferent widths and to provide bonding openings for plaster in the armsthemselves.

2. A metal corner bead section provided with a substantially flat bodymember having arms extended from one of its edges at an angle to saidbody portion and normally lying in the plane of said body portion withadjacent arms spaced apart by a distance substantially equal to thewidth of one of said arms, and which forms a bonding opening for plasterbetween the arms, fingers integral with said arms and struck therefromand normally lying in the plane thereof, said fingers being foldedsubstantially parallel with said arms and projected beyond the loweredge thereof to form therewith arms of a predetermined length but of different widths and to provide bonding openings for the plaster in thearms themselves.

3. A metal corner head section provided with a substantially flat bodyportion having arms extended from one of its edges at an angle to saidbody portion and normally lying in the plane of said body portion withadjacent arms spaced apart to form bonding openings for the plasterbetween said arms, fingers integral with said arms and struck therefromand normally lying in the plane thereof, said fingers being foldedsubstantially parallel with said arms and projected beyond the loweredge thereof to form therewith arms of a predetermined length but ofdifferent widths and to provide bonding openings for the plaster in thearms themselves.

In testimony whereof, I have signed my name to this specification.
